Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Didomi

Pricing is based on monthly unique visitors and is not published, so a large publisher cannot estimate cost before entering a sales process, and traffic spikes translate directly into billing surprises.
Consent banners depress measurable traffic by design, and Didomi cannot prevent that, so publishers moving from a non-compliant banner should expect an immediate drop in tracked users and attributable conversions.
Certification is a moving target: Google and IAB update requirements periodically and each version change forces integration work on your side, not only on the vendor's.
Connected TV consent collection depends on the app platform and remote control interface, and implementations are considerably more involved than a web banner, often requiring per-platform development.
The wider privacy suite beyond consent is thinner than dedicated privacy platforms, so an organisation needing data subject rights automation and data mapping usually buys a second vendor anyway.

Harvey

There is no published pricing anywhere, and no self-service tier at all, so even qualifying for a quote requires an enterprise sales process most small and mid-size firms cannot justify starting.
25-seat minimums put it structurally out of reach for solo, boutique and most mid-size firms regardless of interest.
Reported additional platform fees on top of the headline per-seat licence mean the effective total cost is materially higher than the quoted seat price alone suggests.
As a well-funded, fast-growing AI vendor, its product and pricing model are still evolving quickly, which is a real risk for a firm signing a multi-year enterprise contract now.
Being trained and marketed specifically for BigLaw workflows means smaller firms evaluating it are comparing themselves against a product that was not built or priced with them in mind.
